Yeah, I was wondering why GSP doesn't do that kind've stuff more often. It's perfectly legal and you can get alot of damage done to the body. But I'm not sure adding knees to the ground would help out any more then albows to the ground!

Well obviously few things that Chael Sonnen can be taken seriously, he says the moisture absorbing mat they use on the floor of the Octagon scrapes your knees up like crazy and makes it difficult to walk afterwards.

If that's true then extended ground combat with top control probably makes you take a second thought in regards to throwing a knee.

fedor wouldn't fight any of them and even if he did he would get raped

Ya he would get raped by those guys under pride rules. I'm willing to put any money if pride was still around and u put lesnar in the ring with Fedor, fedor would beat the living shit out of him. In the ufc i can lesnar pushing fedor to the cage and take him down. But in a ring he pushes fedor into the ropes fedor would bounce back and reverse the technique.
